Hi Bill, You've got it 99%. I want to roll E back to say B, and keep G intact. I really don't care about C, D or F. Essentially, B is where I want to roll back to, but in case B's data copy doesn't improve what I'm trying to fix I want to have copy of G's data around so I can go back to how it.
My order of operations would be something like this: 1.) Snapshot filesystem to preserve current state (snapshot F). 2.) Create clone of F (clone G). 3.) Roll the filesystem back to snapshot B. 4.) Maintain clone G data even though filesystem is at B. My concerns are: 1.) If I rollback to B after creating the clone, it will erase F and thereby the dependent clone G. 2.) If I promote the clone G, G will be the active filesystem data copy, when I want B to be the active data copy, I just want to keep G around. I apologize that this is coming out so confusingly. Please let me know if this is clear at all. I guess in a simple way, you could say I'd like to be able to rollback to any particular snapshot without having to lose any newer snapshot. Thereby giving the ability to roll-forward and backward. Thank you in advance very much!
